The PI-980 series complements the recently released Aera
Transformer(TM) 780/7800 series of digital MFCs, allowing fabs and
OEMs to standardize on the latest technologies from Aera across
multiple process steps and varied application requirements.

Further, the PI-980 MFC enhances overall system cost of ownership
by eliminating the need for a number of traditional, costly gas-panel
components. Its multi-gas, multi-range functionality dramatically
reduces inventory requirements.

Steve Rhoades, executive vice president, Products and Operations,
noted, "Our new PI-980 MFCs with NeuralStep technology are a
best-in-class addition to Aera's world renowned line of MFCs. This is
a great example of AE's continuing commitment to technology
innovation. It's also a great example of AE's continuing commitment
to increasing our customers' competitive advantage."
